Description and Characterization of Actinomycetes
were isolated from soil samples collected from the rare ecosystems, namely, (i) Thar desert, Rajasthan; (ii) Rubber forest, Kerala; (iii) Coffee plantation, Kerala; (iv) Western Mountain, Thirukurungudi, Tamil Nadu; (v) Thotabeta hills, Tamil Nadu; (vi) Siruvani hill area, Tamil Nadu; (vii) Yercaud hills, Tamil Nadu; and (viii) Munnar hill area, Tamil Nadu.
There are endophytic bacteria, fungi, and/or actinomycetes
whose isolation from the plant tissues has been a challenge since the studies on endophytes started.
Along with the different types of marine bacteria, actinomycetes
also play an extensive role in the pharmaceutical and medical industry for their capacity to produce secondary metabolites with diverse chemical structures and biological activities.
have long been reported as important source of biotechnologically important compounds.
Bovine farcy causing actinomycetes
isolated from zebu cattle in eastern Africa were found to belong to the genus Mycobacterium and not to Nocardia [4-10].
Punjab University has awarded PhD degree to Muhammad Abbas S/o Muhammad Sharif in the subject of Microbiology and Molecular Genetics after approval of his thesis entitled 'Antimicrobial and Anticancer Potential of Actinomycetes
Isolated from Himalayan Mountain Range, Pakistan'.
What makes WDB unsafe is the growth of a group of single cell microbes invariably found in WDB that make specific compounds that can cause inflammation (called inflammagens) or toxins made by bacteria (endotoxins or exotoxins), fungi (mycotoxins), mycobacteria (mycolactones) and actinomycetes
. Add to the rogues' gallery of en-suite bad actors the very small cell wall fragments of fungi (beta glucans and mannans), fungal and bacterial enzymes/proteins (hemolysins, spirocyclic drimanes and proteinases), not to mention the result of each of these non-living elements acting synergistically, one with another.
are gram-positive, weakly acid-fast aerobic actinomycetes
that are ubiquitous in the environment; 29 species have been identified (1).
Potato dextrose agar medium-PDA (TUITE, 1969) with the addition of 250 ppm of tetracycline was used to isolate fungi; NYDA for isolating bacteria; King's B medium-KB (KING et al., 1954) to isolate fluorescent Pseudomonas spp.; Starch casein agar modified medium-MSCA (VARGAS GIL et al., 2009) to isolate actinomycetes
; and Malt extract agar medium-MEA (MARTIN, 1950) for the selective isolation of Trichoderma spp.
All the diluted samples were cultured on two plates of different culture media, inorganic salts starch agar (ISP4) media supplemented with cycloheximide (100pg/ml) and colistin (5pg/ ml) for Actinomycetes
; and tryptone soya agar supplemented with cycloheximide (30pg/ml) and penicillin (100pg/ml) for Eubacteria.
